الأسئلة الشائعة

A NEMA 4 enclosure is a type of protective enclosure rated by the National Electrical Manufacturers Association (NEMA) to provide protection against windblown dust, rain, splashing water, and hose-directed water. It is commonly used for industrial control panels, electrical junction boxes, and outdoor equipment where environmental resistance is critical.

Both NEMA 4 and NEMA 4X enclosures offer the same level of protection against water and dust. However, NEMA 4X يضيف corrosion resistance, making it more suitable for outdoor, marine, or chemical processing environments.

  • Carbon Steel (Powder-Coated) – Cost-effective for general industrial applications.

  • 304 / 316 Stainless Steel – Offers excellent corrosion resistance for outdoor or food-grade use.

  • ألومنيوم – Lightweight and corrosion-resistant, ideal for marine or telecom applications.

Yes. NEMA 4 enclosures are rated for protection against hose-directed water, splashing, and limited ingress during heavy rain or washdowns. While not submersible (like NEMA 6P), they are IP66-equivalent, making them suitable for most wet industrial or outdoor conditions.

Absolutely. NEMA 4 enclosures are designed for outdoor use and are commonly used in HVAC controls, solar installations, traffic systemsو outdoor electrical boxes. For areas with high salt or chemical exposure, we recommend NEMA 4X stainless steel enclosures.

Yes. NEMA 4 enclosures are approximately equivalent to IP66, which means:
